The phonological vowel and consonant length distinctions in languages such as Hungarian may provide a constraint on the degree to which prosodic structure can influence speech segment duration. Here we show that, like many other languages, Hungarian does mark prosodic structure with durational variation, in particular, utterance-final lengthening. There is an influence of phonological vowel length on the locus of utterance-final lengthening: long and short vowels are lengthened in absolute-final syllables; long vowels are also lengthened in penultimate syllables. Lengthening within pitch-accented words, observed in languages such as English, appears absent, however. Furthermore, we do not find support for the inverse relationship between word length and stressed vowel duration suggested by previous studies. 1. Minimize

We investigate the perception of phonemic vowel quantity contrast and its relation to word stress and vowel quality in Slovak, and fill the gap of missing experimental perception data for this language. We observe that both prosodicallydriven undershoot of unstressed vowels and the functional load affect the perception of quantity contrast. Vowe...

We investigate the perception of phonemic vowel quantity contrast and its relation to word stress and vowel quality in Slovak, and fill the gap of missing experimental perception data for this language. We observe that both prosodicallydriven undershoot of unstressed vowels and the functional load affect the perception of quantity contrast. Vowel quality plays some role in quantity identification for high vowels (/u/ and unstressed /i/) but Slovak seems to retain a robust quantity contrast for all examined vowel qualities.

In Hungarian, focussed elements occur in certain syntactic positions. Because of this limitation, prominence marking by means of prosody is less salient than in languages where focus can be expressed by accent shift without changes in word order.

In Hungarian, focussed elements occur in certain syntactic positions. Because of this limitation, prominence marking by means of prosody is less salient than in languages where focus can be expressed by accent shift without changes in word order. In this study, we examined Hungarian utterances that were identical in their segmental structure, but differed with regard to their semantic and pragmatic interpretations. Our aim was to see to what extent prosodic prominence marking is used, and which pitch accent patterns can occur in different sentence positions in this language. We found that (1) deaccentuation of content words was relatively seldom, (2) accented words were often preceded by a break, (3) the number of accent distribution patterns was limited, as was the number of (4) pitch accent types in utterance-initial and-final position: initially, late peaks dominated, whereas in final position most accent tones were falling ones. We argue that these uniform patterns are probably due to neutralisation processes. Minimize

In this study we compare human ability to identify vowels with a machine learning approach. A perception experiment for 14 Hungarian vowels in isolation and embedded in a carrier word was accomplished, and a C4.5 decision tree was trained on the same material. A comparison between the identification results of the subjects and the classifier showed that in three of four conditions (isolated vowel quantity and identity, embedded vowel identity) the performance of the classifier was superior and in one condition (embedded vowel quantity) equal to the subjects’ performance. This outcome can be explained by perceptual limits of the subjects and by stimulus properties. The classifier’s performance was significantly weakened by replacing the continuous spectral information by binary 3-Bark thresholds as proposed in phonetic literature [8]. Parts of the resulting decision trees can be interpreted phonetically, which could qualify this classifier as a tool for phonetic research. Minimize

According to most current theories, the Hungarian vowel system involves 14 vowels that correspond to seven vowel pairs, each differentiated by quantity. However, there are phenomena both on the phonological and the phonetic level which suggest that for low, mid, and high vowels a separate evaluation of the quantity opposition is necessary. In order to test this, we conducted a perception test, in which embedded and isolated vowels spoken by a native Hungarian speaker were to be identified by native listeners. The results show that the perception of vowel length and vowel quality (i.e. the formant structure) closely interacts in Hungarian. Low vowels, for which short and long realisations differ in quality, i.e. in vowel height, were seldom identified incorrectly. For embedded high vowels, duration was not obviously regarded as a crucial cue for identification by the subjects, nor were they clearly differentiated by the speaker. Mid vowels showed a mixed behaviour: they were differentiated regarding their duration and formant structure in production, however, this information was only partly used by the listeners. The fact that vowel quantity distinction in Hungarian is only maintained where there is a perceivable quality difference shows that the role of quantity is not as dominant as it has been regarded for long.

Abstract: This study addresses the questions how to parameterize (1) aspects of fundamental frequency (F0) register, i.e. time-varying F0 level and range within prosodic phrases and (2) F0 discontinuities at prosodic boundaries in order to predict perceived prosodic boundary strength in Hungarian spontaneous speech. For F0 register stylization we propose a new fitting procedure for base-, mid-, and toplines that does not require error-prone local peak and valley detection and is robust against disturbing influences of high pitch accents and boundary tones. From these linear stylizations we extracted features which reflect F0 boundary discontinuities and fitted stepwise linear regression and regression tree models to predict perceived boundary strength. In a ten-fold cross-validation the mean correlation between predictions and human judgments amounts up to 0.8. 1 Minimize

Syllable cut is said to be a phonologically distinctive feature in some languages where the difference in vowel quantity is accompanied by a difference in vowel quality like in German. There have been several attempts to find the corresponding phonetic correlates for syllable cut, from which the energy measurements of vowels by Spiekermann (2000) proved appropriate for explaining the difference between long, i.e. smoothly, and short, i.e. abruptly cut, vowels: in smoothly cut vowels, a larger number of peaks was counted in the energy contour which were located further back than in abruptly cut segments, and the overall energy was more constant throughout the entire nucleus. On this basis, we intended to compare German as a syllable cut language and Hungarian where the feature was not expected to be relevant. However, the phonetic correlates of syllable cut found in this study do not entirely confirm Spiekermann’s results. It seems that the energy features of vowels are more strongly connected to their duration than to their quality. 1 Minimize
